ENVELOP-MAGHINE Specification of Letters Patent.

Patented Oct. 27, 1908.

To all 2 :71am it may concernf lie it known that we, Fnnn F. FLAGG and Greener: SMITH, both of \Vorcester, in the county of Worcester and State of Massachusetts, and .both citizens of the United States, have invented a new and useful Improvement in Envelop-Machines, of which,

the following is a specification.

in Letters Patent of the United States No. 843,707, dated February 12, 1907, and granted to John A. Sherman, there is described a plunger used in connection with a creasing table and folding box of an envelop machine of a type well known; The plunger has an opening surrounded. by a casing which forms a hopper for a pile of transparent blanks or patches, the patches being kept from falling through the opening by clips arranged around the edge of the opening. The patches are intended to' be at tached to an envelop having an opening in its face. the edges of the opening being gm'mned, the patch closing the opemn'g, an by reason of its transparent character allowing the address upon .the incglosure to be read,

so saving the trouble of addressing the en-" velop.

Our invention consists in means for centering and supporting patches of a similar character in the plunger so that the lower patch of the pile which comes in contact with and is to be attached to the envelop blank about to be folded will be the more easily attached and withdrawn from the bottom of the pile while the rest of the patches will be properly supported within the casing, and also in a carrier constructed to cooperate with such a plunger Without reducing the speed of the machine.

Our invention will be understood by reference to the drawings, in which- Figure 1 is a top view of a plunger em bodying our invention, Fig. 2 being an under view thereof, Fig. 3 an end view, a portion of the edge being broken away to show the.

construction of one of the posts. Fig. 4 isa sectional elevation on line 44 of Fig. 1, and

.The plunger A is operated in the usual manner. It is rectangular and of any ordinary outline to conform to the shape of the envelop and to the opening A in the creas-' ing frame by means of which and the plunger the envelop blank is to be creased.

A is the plunger rod from which the plunger is hung. This plunger is provided with a feed opening A Vertical rods B, B are mountednear each end of the opening and to the bottom of each rod is attached a clip 6 to form a support for thepile of patches C contained above it. as guides to keep the blanks properly piled and in proper place to be fed and also to engage the patch and assist in holding the patches in the plunger.

The preferred shape 'of the patches is shown in Fig. 5 where the patch is lettered V and it isthereshown attached to the inner surface of the envelop blank D. The patch is approximately rectangular and of sufiicient size to close the opening in the envelop. Near each end it is narrowed as at c and at each end it is provided with ears 0 thus. forming notches which fit around the rods B; B (or around the rods B in the modification below referred to), engaging them more or less closely and cooperating with these rods to hold the patch from endwise movement. This is a convenient way of holding the ends of the patches The rods B, B serve from longitudinal movement. Thus the pile of patches is properly supported at each end, while there will be a tendency to sag at-the middle on the part of the lower patches of the pile. The patches, however,

cannot fallout because of the engagement of a the cereal with the rods B, B As the plunger moves downwardly upon an envelop blank the middle or sagglng por-,

tion' of the lower patch (see Fig.4) strikes the gummed surface on the envelop blank first, and as the plunger rises the lower patch by reason of its engagement with the blank is drawn out from the plunger, the ears 0 being drawn out from behind the rods B, B. The patch is then pressed in place by the. pressure of thefolders as they fold the envelop. These folders are indicated at-E and are operated in the usual way, the bottom of the box being lettered E We prefer to' make two of these rods adjustable in order .to conform to any possible irregularity in the cutting of the patches. For this purpose I v I, A M

instead of being fixedly supported in the plunger the rods B are supported in grooves b in the walls of the plunger opening and set screws 7) are provided which pass through the edge of the plunger, the end of each screw being attached to its rod B so that as the screw is turned the foot of the rod is moved either in or out as the case-may be. The heads of the screws should not project beyond the outer wall of the plunger, otherwise they will strike the walls of the creasing frame.

While we have shown four rods forming a skeleton inclosure for the blank pile, it is evident that a casing may be provided instead the walls of which are so shaped to engage ears or their etpiivalents. and it is also evident that the opening of the plungermay be of any convenient shape provided clips such as re shown at Z) are mounted on the plunger to support the blanks, and means are provided to engage the edges of the blanks and hold them from endwise movement as described. For example, we have shown" in Fig. 6 another construction wherein the patches though differently shaped are sii'nilarly held. In this constructimi there are but. two ror s which we have lettered 3*, each carrying clips Z), and in this case the ears 0 on the patches turn inwardly instead of outwardly so that each pair of ears hug around the same rod B. The rods in this case are approximately of the same shape as the space between the ears. The principle of operation in each case is the same in that the blanks are held from falling downward by clips and from endwise motion by rods past. which, however, they may slide or be pulled as occasion requires, the pile of patches in each case being pressed back into their nor- 'mal or proper position by the pressure of the plunger on the botton'i of the folding box each time the plunger strikes the envelop blank. The improvement in the carrier which renders it possible to use this mechanism without interfering with the speed of the machine is shown in Figs. 7, S and 9. .In each case F represents the ways in which the carrier caused to slide by means such as is usual in such cases. These ways are provided with crossbars F F", which together with the portion of the ways lying between them form the creasing frame, this being the usual construction in every respect except that. the cross-bar F has a slight. elevation for purposes to be hereinafter described.

The carrier G performs the usual function of carrying the blank from the picker to the plunger. Its forward end 9 is cut away at 9 so as not to engage with the rising picker it moves forward. "It is mounted as usual on slide-bars g and is operated in the usual way. Instead ofthe usual construction of that. part. of the carrier which supports the back flap of the envelop, we provide swingmg wings each comprising two arms H, 11 each wing being pivoted in a slide-bar at H The-arms H support the back flap end of the blank and the arms 1 engage with pins /L on the ways F, F to spread the wings against the stops [L3 as the cam moves rearward towards the creaser frame and with pins 72., h mounted onrods if, if at the forward end of the ways F F to close the wings again so that they may be in position to receive a fresh blank. For this purpose the arms H are preferably made wedgeshaped. 3y this means a clear passage is allowed so that the carrier can start forward before the plunger clears the creasing frame in its upward movement.

' It is evident that the wings may be spread by engagement of the parts H with the bars B, B as the carrier moves forward without the intt-ufvention of the pins 71, h, but we prefor to provide especial means for the purpose as shown. lVe have provided the cross-bar F with the elevation f" and have bent the arms H, H to ride over this elevation as shown in Fig. 9, as this brings the gummed surface to which the patch is to be attached into a higher position for engagement with the patch as the plunger in its descent will strike that portion of the blank first and cause the engagement of the patch with it.

it is evident that the shape of the wings may be changed and different means be adopted for moving them. So far as we know the use of a carrier having a movable part or parts for supporting a portion. 'of the blank from below is entirely new with us and it. has added n'iaterially to the speed of the nun-lune.

The advantageof our improvement over the invention shown in the patent above referred to lies mainly in the fact that. the

. patches archeld near the corners so that the middle portion of the lower patch is free to engage with the gummed surface of the envelop blank, and when engaged will pull the ends of the blank from their retaining means, and the retaining means may be any means which will support the ends of the blank from falling out of the plunger while allowing the middle portion to and strike the gummed surface of the blank in advance of the rest of the patch.

What we claim as our invention is:
